Atlantic Stone is a Chinese volcanic hard rock of the porphyry/rhyolite family with a dark grey to anthracite ground tone and a fine mineral structure. Acid-resistant and frost-proof — used for floors, stairs, façades and prestige external architecture.
Atlantic Stone works through a deep, quiet dark grey to anthracite ground tone with a fine mineral structure. Occasional pale mineral points and subtle calcite veins stand out in the dense matrix — a restrained, almost technical feel that does not push the material into the foreground but works as a quiet, dark background. It is precisely this legibility that makes the stone interesting for floors, stair arrangements, façade cladding, pool surrounds and prestige external architecture — wherever a consistently dark, robust material effect is called for.
Geologically, Atlantic Stone is a volcanic hard rock from Chinese deposits. In the natural stone trade the material is assigned to the porphyry or rhyolite family — both classic volcanic rocks formed by the solidification of silica-rich magmas at or near the earth's surface. The fine-grained, dense structure and the dark ground tone are typical of this rock group. At ROSSITTIS, Atlantic Stone runs in the basalt family, which covers all volcanic natural stone ranges.
Technically, Atlantic Stone benefits from this volcanic mineralogy: acid-resistant, frost-proof, high compressive and flexural strength. Wine, lemon, vinegar or acidic bathroom cleaners leave no etch marks on the polished surface — a decisive advantage over calcareous marbles and limestones. Water absorption is low, and frost resistance is very good, as is typical for the volcanic rock family. The stone is therefore outstandingly suited to external applications, pool surrounds, terraces and façades, where many marbles would fail.
At ROSSITTIS we carry Atlantic Stone as an unsized slab for wall cladding and floor applications, in tiles for floor and wall surfaces, as tread and riser, window sill, skirting, pool surround, façade cladding and project-specific cutting. The surface finishes currently held in stock are listed in the »Finishes« block further down — polished emphasises the depth and the rich anthracite most strongly and is the classic choice for prestige interiors and bookmatch wall surfaces.
Compared with classic Italian porphyries such as Porfido Valcamonica or Porfido Rosso, the dark, almost black ground tone makes Atlantic Stone appear cooler and more modern. Compared with basalt from Italy or Vietnam, the material brings a slightly lighter, livelier mineral structure. For modern external architecture with a dark, robust material character, Atlantic Stone is a very fitting choice. Anyone looking for maximum drama in a black stone is better served by a black granite such as Nero Assoluto or a black marble such as Nero Marquina.

Finishes
Atlantic Stone is available in a range of finishes. The finish affects appearance, feel and the care it needs.
Poliert
Politur erzeugt eine glänzende Oberfläche mit höchstmöglicher Farbintensität und ausgeprägter Tiefenwirkung der Porphyr-typischen Mineraleinschlüsse. Als Silikatgestein säurebeständig und pflegeleicht. Eine repräsentative Veredelung für Wandverkleidungen, Küchenarbeitsplatten und gestaltete Sichtflächen mit kraftvoller Materialwirkung.
Satiniert
Die Oberfläche wird gebürstet — weichere Minerale werden gezielt entfernt, es entsteht eine leichte Tiefe mit mattem Erscheinungsbild. Wie bei Granit pflegeleicht und alltagstauglich, säurebeständig. Eine zurückhaltende Veredelung, die den charakteristischen Porphyr-Mineralien eine subtile, matte Bühne gibt.
Poliert RS satiniert
Beidseitig einsetzbare Platte: polierte Sichtseite mit höchstmöglicher Farbintensität und Spiegelglanz, Rückseite satiniert mit matter, gebürsteter Anmutung. Eine flexible Konstruktion für Anwendungen, in denen Glanz- und Mattseiten je nach Einbauumgebung gewünscht sind — säurebeständig als Silikatgestein.
Care & fabrication
As a volcanic hard rock, Atlantic Stone is completely acid-resistant — wine, lemon, vinegar, coffee or descalers leave no etch marks on the surface. That is the decisive difference from calcareous marbles and limestones and makes the material easy to look after in the kitchen, bathroom and outdoors.
For kitchen worktops and vanity tops we recommend a single silane- or polysiloxane-based sealing. It prevents the penetration of oily and greasy soiling, which on dark surfaces can otherwise become visible as pale shadows. For interior wall and floor surfaces a sealer is optional, but it is worthwhile in heavily used areas.
Daily care is carried out with clear warm water and a soft microfibre cloth. For heavier soiling, use a pH-neutral natural stone cleaner. Hot pots and pans can be set down directly — volcanic rocks are heat-resistant.
Fingerprints and water marks are more visible on polished dark stone than on pale or textured surfaces. The surface finishes currently held in stock are listed in the »Finishes« block further down.
Outdoors, Atlantic Stone is frost-proof and stable over the long term without further protective measures. Rinse off de-icing salt, pollen or leaves with clear water in spring; a stone cleaner is enough once or twice a year.
Frequently asked questions
Is Atlantic Stone suitable for a kitchen?
Yes, very much so. As a volcanic hard rock, Atlantic Stone is acid-resistant — wine, lemon, vinegar or coffee leave no etch marks. A single sealing gives additional protection against oily and greasy soiling. For family kitchens the satin-honed variant is more tolerant in everyday use than the polished one, because fingerprints are less visible.
Which finishes are available for Atlantic Stone?
The surface finishes currently held in stock are listed in the »Finishes« block on this page.
Where does Atlantic Stone come from?
Atlantic Stone comes from Chinese deposits. Geologically it is a volcanic hard rock of the porphyry or rhyolite family.
Is Atlantic Stone a marble or a hard rock?
Atlantic Stone is not a marble but a volcanic hard rock of the porphyry/rhyolite family. In fabrication and maintenance it behaves like granite or basalt: acid-resistant, frost-proof and very well suited to external applications.
How do I clean and care for Atlantic Stone?
Daily cleaning with clear water and a microfibre cloth is sufficient. For heavier soiling, use a pH-neutral natural stone cleaner. A single silane-based sealing protects against oily stains, which stand out more visibly on dark stone.
Is Atlantic Stone frost-resistant and suitable for outdoor use?
Yes, completely. Volcanic hard rocks have a very low water absorption and are frost-proof without further protective measures. For pool surrounds, terraces and external treads with slip resistance requirements, a matt, textured surface finish makes more sense than polished.
Atlantic Stone or basalt — which suits better?
Both are volcanic hard rocks with a similar maintenance logic. Classic basalts are often more homogeneous and quieter in slab pattern; through its porphyry/rhyolite characteristics, Atlantic Stone brings a somewhat livelier mineral structure. For a consistently quiet black material image, basalt; for more material character, Atlantic Stone.
